MULTILAYERED HEAT-SEALABLE PLASTIC FILMS

摘要

The invention relates to heat-sealable plastic films PF for sealing plastic containers, built up from a mixture M of from 1 to 99 parts by weight of a high-impact polystyrene resin PS and from 99 to 1 parts by weight of a copolymer P comprising: p1) from 20 to 90% by weight of methyl methacrylate and/or ethyl methacrylate, p2) from 10 to 80% by weight of at least one monomer of the formula I: in which R1 is an alkyl radical having from 3 to 24 carbon atoms, and p3) from 0 to 10% by weight, preferably from 1 to 8% by weight, of a monomer which can be copolymerised with monomers p1) and p2), but differs from monomers p1) and p2), where monomers p1), p2) and p3) add up to 100% by weight.
